I'd assume that they would vent the steam and douse the fires
beforethat stage. Certainly Jack Phillips, the Titanics radio
operator, was sending messages that he couldn't read other stations
due to steam and air noise.
How exactly does one do that?
It's on a par with "opening the seacocks"
The boilers would have safety valves which no doubt vent somewhere
safely. Manually open them? Or far more likely have another valve
that opens to a safe vent. Dousing the fires might be slightly more
tricky due to thermal shock on the cast iron parts and not wanting to
produce too much steam that the flues/funnels couldn't cope with.
There are safety valves. They would lift if the engines stopped. They do
not vent to the funnels.
They vented up the side of the funnel and would have had easing gear,
which allowed them to be opened manually.
But there's no way you would want to remove tons of water at steam
temperature. It is the ultimate catastrophy for a steamboiler. The
furnace tubes would overheat and collapse in minutes.
I doubt that any of the engineers would have expected the boilers ever to
be needed again, once they saw the extent of the damage to the ship.

Dunno, given that it was supposed to be unsinkable, and brand new,
its much more likely that they would have been hoping that it really
was unsinkable and that they would be used again eventually.

Boiler rooms 5 and 6 were at risk from the flooding and cold sea water
hitting a boiler under pressure would cause an explosion, to add to their
problems. It was vital to reduce pressure in those boilers as *quickly as
possible, hence the venting. In fact, all boilers not needed to run pumps
or dynamos would probably have have had an emergency shut down.

Sure, but its likely they would have tried to avoid ruining them
completely so they would have had to be replaced if it hadn't sunk.

And how would you "douse the fires"? You would close the dampers but the
fires would take hours to burn the tons of coal in there.
The fires would have been raked out onto the boiler room floor.

Where they would have produced quite a bit of steam when the water came in.- Hide quoted text -

How does cold water cause a steam explosion?
